We propose a credit-based resource allocation technique for wireless systems with dynamic spectrum access (DSA) capability, such as multichannel wireless sensor networks. The proposed technique is robust against selfish and malicious behaviors by achieving high performance independently of what users choose to pursue as their objectives. It also improves fairness by ensuring that different users are allocated equal amounts of spectrum service. Using simulations, we show that the proposed

We also show that it reduces the standard deviation of users' amounts of received service drastically, and hence, improves fairness among users substantially.
